Students and lighting professionals interested in advancing their knowledge and careers in lighting have two new educational options. The LRC is now accepting applications for the nine-month master’s degree and doctoral degree programs to begin next fall.

“These new options provide flexibility and diversity to meet the needs of any lighting professional who desires further education in the field,” said Dan Frering, LRC manager of education.

The LRC is evaluating light-emitting diode (LED) technology for use in commercial display freezers. The study, funded by the New York State Energy Research and Development Authority (NYSERDA), will evaluate performance, energy savings, shopper preferences, and product sales for this technology compared with the fluorescent lighting currently found in supermarket freezers.

The LRC is collaborating with GE’s GELcore, the Golub Corporation (Price Chopper supermarkets), and Tyler Refrigeration (a division of Carrier Corp.) on this project. The team recently installed a four-door freezer with a prototype LED lighting system in the frozen-food aisle at an Albany, N.Y.-area Price Chopper supermarket.

As a follow-up to the very successful series of Internet-teleconference seminars presented earlier this year, the LRC will offer additional seminars beginning in January 2005. These seminars will use a similar format to the previous LIVE! from the LRC programs, providing cutting-edge information on lighting in an easily accessible, interactive format.

New, unified system of photometry addresses lighting for mesopic vision

Lighting specifiers selecting outdoor luminaires typically consider the luminous efficacy of a fixture in order to gain maximum energy efficiency. However, the problem, LRC researchers say, is that the lumens per watt value is based on a photometry system that does not consider how the human visual system works at light levels typically found outdoors at night. To correct this problem, LRC researchers have proposed a new system of photometry designed to characterize light at any light level.

LRC establishes ‘Daylighting Controls Practicum’

One of the missing links in many daylighting designs is the inclusion of a control system that effectively turns off or dims electric lighting in response to available daylight. To address this problem, the LRC is developing a program that will train lighting decision makers to make better use of controls to save energy in response to daylighting.

The Daylight Dividends program recently released the first of three case studies that evaluate daylighting designs in nonresidential buildings. The first study explores effective design strategies for schools through an assessment of one school built specifically to harvest the benefits of daylight.

LRC organizes ENERGY STAR® socket and ballast base design competition

The U.S. Environmental Protection Agency (EPA) and the American Lighting Association (ALA) want to make it easier for consumers to use energy-efficient residential light fixtures.

Entries submitted for a new competition, organized by the LRC with support from the EPA, are now under review to select the best line-voltage socket and ballast base design for compact fluorescent lamp (CFL) fixtures.

Do you have a lighting question? If so, NLPIP most likely has the answer. The National Lighting Product Information Program recently expanded its online FAQ section to include nearly 200 questions and answers in a broad range of lighting topics. Examples of FAQs include:

  • Can a T5 lamp replace a T12 or T8 lamp?
  • Can LEDs be dimmed?
  • How hot are halogen torchieres?
  • How can task lighting maximize energy savings?

A short answer is provided for each question along with a link to the NLPIP publication that covers that topic. In some cases, a link to a more detailed answer is provided. Online visitors can view the questions and answers for a particular topic by selecting one of several categories.

The FAQs were developed from previously published NLPIP Lighting Answers publications, which help lighting professionals, contractors, designers, building managers, homeowners, and other consumers find and effectively use efficient, quality products that meet their lighting needs. New FAQs will be added as new Lighting Answers become available.
